CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 428,689, dated May 27,1890.

Application filed January 28,1890. Serial No. 338,374. (No model.)

To all whom', it mag/concern:

Be it known that I, ROBERT T. MORRISON,

Jr., of Medina, in the county of Medina and p a front end elevationpartly in-section. Fig.

2 is a side elevation in section on line no, Fig. 3. Figs. 3 and et areplans in section on line y y, Fig. 2, showing, respectively, differentpositions of the coupler.

A represents the draw-head, and B the hook-coupler with which eachdraw-head is provided, the coupler being preferably of forged steel andof approximately the form shown, and having a shoulder or hook b andadjacent incline b', the coupler being pivoted on vertical pin C of thedraw-head. Each draw-head has a chamber A', in which the coupler of anopposing draw-head may operate, this chamber being of such verticaldimensions as will accommodate the opposing coupler with cars ofdifferent heights, loaded and unloaded, and variationsof the tracks,dac. The draw-head is provided with a lateral recess A2, this recessopening into cha1nber A midway thereof vertically, the recess of thedraw-head being adapted to receive with an easy iit its own coupler whenthe latter is swung back in uncoupling the cars. Pin C is provided withspline c, that fits in groove b2 of the coupler, whereby the coupler maybe swung laterally by turning O on its axis. Above the draw-head pin Cmay be provided with an arm O', to which arm may be attached one or morerods e', leading to the side or sides of the car, whereby the cars maybe uncoupled by an operator standing on the ground at the side of thecar; also, an extension-rod C2 may be coupled with pin C,

5o this extension-rod extending up, for instance,

to the platform or to the top of the car, where it is provided withhandle or handles c2, whereby the cars may be uncoupled from theplatform in case of passenger-cars,'or from the top of the car in caseof freight-cars. Semi-cylindrical bushings d and a', preferably ofsteel, are inserted from above and below in corresponding recesses inthe top and bottom walls of the draw-head, these bushings fitting theinner side of pin O, and the ends of the bushings engaging the couplertop and bottom, the thickness of these bushings corresponding with thethickness of the coupler at the heel thereof, so as to present an evensurface from top to top of chamber .A' for the engagement of the hook ofan opposing coupler.

The heel of the coupler on the one side thereof is provided with lug B',located as shown, to which lug is fastened a vertical bar D, the latterbeing about as long as will operate freely in chamber A', this bar beingin position to snub back and thereby uncouple theV opposing coupling inturning back the coupler to which bar D is attached. It is evident,therefore,v that by operating pin O both couplers may be turned back, soas to uncouple theoars.

E is a spring-actuated lateral pin adapted to engage the respectivefaces b3 and b4 of lug B', according to the position of the coupler. PinE, by engaging face h3, as shown in Fig. 3, holds the coupler in itsclosed position. When the coupler is swung back into recess A', as shownin Fig. 4-, pin D, by engaging face b4 of lug B', holds the coupler inits open position. Spring d need have but little tension when thecoupler is in position open or closed, the spring being only momentarilystrained in a moderate degree in shifting the coupler, and hence thespring` is likely to last as long as other members of the coupler. Thetop and bottom walls of the draw-head are pierced vertically, as shownat d3, for inserting a coupling-pin (not shown) for coupling withordinary links. In assembling the parts, first the lower bushing isinserted and is held in place usually by means of a driving iit.` Nextthe coupler is placed in position swung back into recess A2, in whichposition the pin` may be inserted, together with the upper bushing. Theparts having been assembled, in turning the coupler to its position forcoupling, spline c is swung under the solid upper wall of the draw-head,and hence the pin can only be withdrawn when the coupler is swung backits full throw into recess A24 What I claim isw l. In a ear-coupling,the combination of a pair of draw-heads and a hook-coupler carried byeach head, each hook-coupler adapted to be hooked simultaneously overand around the hub of the other hook-coupler to lock the drawheadstogether, substantially as set forth.

2. In a car-coupler, the combination of a pair of draw-heads and ahook-coupler carried by each head, each hook-coupler adapted to hookover or around the hub of the other hookcoupler and lock the draw-headstogether, thc hook-coupler which is operated adapted by its engagementwith the other hook-coupler to throw the latter into locked position,substantially as set forth.

3. The combination, with draw-head and coupler, substantially asindicated, such couplcr being mounted on and fastened to a vcrtical pinof the draw-head, of semi-cylindrical bushings inserted in correspondingrecesses of the draw-head, such bushings engaging the rear side of thepin and abutting the coupler from above and below, substantially as setforth.

4. The combination, with draw-head, hookconpler, and pin, substantiallyas indicated, of upright bar connected with the coupler and operatinginside the draw-head in position to engage and snub back the coupler ofan opposing draW-head, substantially as set forth.

5. The combination, with draw-head and hook-coupler, substantially asindicated, of spring-actuated pin adapted to engage shoulders of thecoupler in position to hold thc coupler in position open and closed,such coupler having att-ached a vertical bar for snubbing back anopposing coupler, substantially as set forth.v

In testimony whereof I sign this specifica.- tion, in the presence oftwo witnesses, this 5th day of December, 1889.
